acter whereby a resilient member Vis disposed between a retaining pinand an adjacent side of a draft'sill upon'a draft key whereby when thecoupling key is shifted in a certain longitudinal direction theretaining key will yieldably bear against the adjacent side of thedraft'sill and be prevented by a yieldable member from being shearedfrom con-V nection with the draft key when the cars with which the draftkey is i associated round a .curve in a' direction t-o shiftv the draftkey in said` certain longitudinal' direction. 5

@ther objects will appear hereinafter.

The invention consistsv in the combination and-arrangement of parts tobe Vhereinafter described and claimed.' i Y, n

The invention will be best understood by reference to the accompanyingydrawings illustrating the preferred formof my invention, and in which:l i

Fig. 1 is ,a transverse. Ysection taken through a coupler, illustratingmy. improvei meut applied thereto. f

Fig. 2 is a detailV transverse section on lthe line 2 2 of Fig. 1. .Y

Fig. 3 is a side elevation ofthe fastening key for the draft key, and

Fig. 4 is a plan View of the draft key..V

Referring vmore particularly to the draw-` ing, the numeral 1 indicatesthe center draft sills between which the draft yoke 2 is mounted. Thedraft 'yoke 2 is adapted to Areceive the draw bar 3 and this draw bar,draft yoke a1id|.d1'aft sills are provided. with transverse alignedopenings i` adapted tok receive my improved draft key 5.

This draft key -5 is preferably at, as shown in Fig. 4, and has formedat one end thereof a head '6. The otherl end of the draft key istapered, as at 7, topermit the same' to be readilyV insertedthrough thealigned openings 4. V'Ihis draft key 5 is retained in position-throughthe medium of a U-shaped retaining pin 8. The limb por-V tions of thisretaining keyS pass through v of retaining the Vpin 8 the openingsformed in the 'tapered "end" portion 7 of the draft key and the outerend portions vof thelimbs of the retaining ypin are bent laterally asiat10 for-,the purpose in the y position illus tratedl in Fig. 1. 7

AsV shown in washer 11 is positioned upon the draft key 5 inwardly ofthe retaining pin 8 and disposed between this washer 11 and the ad- Fig.l'uof the drawing a jacent side ofthe draft sills is a Vspringy 'Ymember 12.y This spring member 12 is of lation with the adjacentv sideofthe draft sills 1.` Y Y `While I have illustrated and described thepreferred form of construction for carrying my invention vinto effect,this is capable of variations and lmodification without departing fromthe spirit of the invention. I, there` fore, do not wish to be limitedto the precise details of construction set forth, but desire to availmyself of such variations and modi-v fications f as come within thescope vof the appended claims. Y

Having thus described my invention, what I claim'is:

' end portion lof the draft key, and yieldable means disposed betweenthe retaining key and adjacentkwall of the draft sill.

2. In combination al draftkey defining a head at one end, a removableretaining key for the Vdraft key, and a spring member carried bythedraft key and serving to rei lieve the retaining key of undue strain.

3. In a ydevice of the character described, the combination with a draftsilk-of` a draft key extending transverselyof the draft sill and havinga head formed on one end portion thereof, aretaining key carried bytheother the expansive typefand serves in its principal end of the drniikey1 :l wnlier 'rnrried in' the `(iininiie-v ndjeeent the retainingrkey, und e coil spring carried by the draft' key :rnd arranged betweenthe insher end 7the retaininglr key.
